"Seddon et al.'s single prospective cohort study found that fish intake did not affect the progression to advanced [Age-Related Macular Degeneration] overall, or in a high [Linoleic Acid] consumption group, but did protect against the progression to advanced ARMD in the low (below median consumption) LA consumption group.20 This parallels what was observed exclusively via a significant test for trend in the Seddon et al. study described earlier with reference to its investigation of the influence of the intake of omega-3 fatty acids on preventing the onset of advanced ARMD.15 However, the results from neither study can be used as yet to provide a conclusive answer to their respective research questions. Both require replication and a plausible explanation."
Sounds like they've now got replication and a plausible explanation (see the original post). Prevent blindness: skip the seed oils.
